The feud between Nicki Minaj and Cardi B just turned physical on Friday night, the rappers got into a fight at the Harper’s Bazaar ICONS party that left Cardi bruised.

A star-studded party ended in dramatic fashion when Cardi B and Nicki Minaj nearly came to blows at the Harper’s Bazaar Icon bash in New York City on Friday. In one of several videos posted to Twitter, Cardi B, wearing a red dress, can be seen lunging towards Minaj before throwing a shoe at the rapper as their security teams rush to break it up.

Sources confirm to Variety that it was, in fact, the two hip-hop artists involved in the melee, which happened just as the red carpet shuttered. Cardi B was later photographed with a large bruise above her right eye as she left the party. The back of her dress was also torn. Minaj, who was unharmed in the encounter, was quickly escorted downstairs by Minaj’s security team.

Insiders confirm to Variety that Cardi B’s bump on her forehead was the result of an elbow from one of Minaj’s security guards. New York City Police Department is investigating the matter, which was first reported by TMZ.

Cardi B later wrote about the scuffle on Instagram, “I’ve worked too hard and come too far to let anybody f— with my success!” Without naming Minaj, the “Bodak Yellow” rapper claims a certain someone threatened other artists for working with her, possibly alluding to Minaj’s new track, “Queen of Rap,” which purportedly disses Cardi B.
